I have a CGI script which is being called from many different pages. I need the CGI script to determine which page just called it. This was asked in the chatterbox earlier and it was said to be impossible; HTTP is stateless. But I won't accept impossible, somewhere, somehow someone has an idea of a workaround for this *crosses fingers*. Say we are at www.mypage.com/page1.shtml . We are including the CGI script as an SSI. The CGI has to output the full URL of page1.shtml. ( www.url.com/page.shtml )

Just for the sake of it, I also used 

<!--#exec cgi="../cgi-bin/stats/downloads.pl"-->

[download]
My first idea was using $ENV{"HTTP_REFERER"}. I thought this worked at first but it turns out it only works if the page1.shtml is called directly. This is to say, if you are on www.mypage.com/page2.shtml and click a link to www.mypage.com/page1.shtml the CGI included on page1.shtml will say the referer was "www.mypage.com/page2.shtml" and NOT page1.shtml which it should!

I have used both the SSI and the exec cgi code and using HTTP_REFERER but it's absolutely not working. Can someone tell me how I can get the URL of the page that called it?

I could always pass param values of the URL to the script itself, that would work and I do realize that. The problem is this will be going on hundreds of pages and that's a lot of configuration time involved just to setup each param. If there's some HTTP echo command that can be passed to the CGI, that would probably work beautifully. I KNOW JS can do this, but I'm opposed to using JS all over the site.

Thank you wise monks, yet again.
